invented certain new and useful Improvements in Ty e Writi ng Machines, of which the following is a specification.

This invention relates to paper controlling devices of 'tiipewriting machines and particularly to variety.

ln my co-penclnig application No. 402,583

s disclosed a prov sion for readily and accurately "adjusting the .sheet both endwise and sidewise with} reference to the printing point before the writing begins; a tablet or plate standing on edge above the front portion of the platen and above the printing point, upon which the sheet can readily be adjusted while not clamped by the usual paper rolls which run upon theplaten. Said application discloses a" stop at i the top of the tablet to which the top edge of the sheet may be set, and provision is made for moving the stop' out of the .way to permit the sheet to advance line by line. Adirectrix is shown for guiding the leading edge of the sheet up to the stop, and the directrix and stop are connected tothe same key that re leases the pressure rolls, so that the stop and directrix are thrown into operative position when the rollsare released and vice 'versa. Thetablet and directrix are also adjustable along the platenltoaccommodate different widths of sheets One of the principal objects of the presentinvention is to provide simplified and improved means for handling and controlling the sheet; the construction and operation embodying the same general principles as in said application, but the mechanismbeing simplified and otherwise improved.

In the present construction, a sheet uid 'ing register plate or' tablet is mounted for adjustment 'upand down upon a main plate orbar which extends along the platen frame and is 'fixed thereto, and a directrix is ad,- justable upand down with said sheetguiding plate or tablet; both the directrix and the tablet being also adjustable along the platen? The directrix is mounted directly upon a rock shaft which is connected to the roll' releasing; key,- the directrix being splined "hose of the front strike to the rock shaft and adjustable therealong; the shaft being adjustable up and down with the registering tablet, and having an extensible connection to the key.

In operating the device shown in said application, there is sometimes liability (unless care is taken) of the inserted sheet being disarranged after it is set to the stop and before the pressure rolls clamp the sheets against the platen, since the stop starts to move away from the sheet while the rolls are moving toward the platen.

One object of the present invention is to overcome this difiiculty, and accordingly, I provide alost-motion construction between the key and the stop, to permitthe latter to remain in effective positionuntil thepressure rolls clamp the paper; the reniainder of the return movement of'the key being utilized to throw: the stop but ofthe path of the paper.

Inthe accompanying drawings, Figure .1 I

pressure rolls and stop mechanism, the key being shown, as havin made about half of its return movement. -i 2 is a diagram to illustrate the position 0 the roll-releasing rock shaft when the finger key is"in normal position. Fig. 3 is a view similar'to Fig. 2, but showing thepressure rolls locked away fromthe platen. Fig. 4 is a front elevation of the platen frame of an Underwood front strike writing machine, embodying my present improvements. Fig. 5 is a plan of the same. Fig.6 is a plan to illustrate the directrix in effective position, as at Figsi-l and 9. Fig. 7 is a perspective of one end .of the register plate or tablet and the directrix associated therewith, showing particularly how., the directrix is yieldingly detained in normalposition. Fig. 8' man end elevation of the platen frame and other parts, showing the same in'normal. position.

Fig. 9 is an end elevation showing the rolls releasedfrom the platen, and the sheetssto'p in: effective position. Fig. 10 is a perspective viewof the sheet registering plate or tablet. Fig. 11 is arear view of one of the keepers or guides within which are confined the vnuts that secure the tablet where adjusted, Q j I v The cylindrical-platen l is mounted by.

means ofan axle ,2in the ends 3, 74 of. a

platen frame 'farming part of a carriage? Mounted on edge in front of the platen is a tablet 7, which is nearly vertical, inclining upwardly and a little forwardly, and standing above the front side of the platen and over the point where the types 8 strike the paper.

A bill or sheet of paper 9 is inserted be-.

hind the platen and around the under side of the same, while the usual pressure rolls 10, 11 are released, Fi 9. v The leading edge of the sheet rises in front of the tablet 7, and

the operator may, by touching the leading its lower to its upper edge, and serves to guide the leading edge of the sheet 9, up

against the stop ledge 12. The directrix is formed with slight holes 13 and is substantially shorter than the tablet 7, to give the operator access to the side edges of the sheet 9 to adjust the same.

Before inserting a sheet, the operator depresses a key 1 1 from the Fig. 8 to'the Fig. 9

osition'. Said key 1 1 is mounted upon a ey shaft 16, which has an arm 17, to which is pivoted at 18 an extensible link comprising a stem portion 19, and a block 20 in which the stem 19 is adjustably secured by a screw 21. The upper end of the link is formed with a vertical loop 22 to engage a wrist 23 carried upon an arm 24 upon said rock shaft. 15. VVhen' the key 14 is raised, the rock shaft is turned .to the Fig. 8 position, and the dlI'GCtIlX 13 swung forwardly to clear the sheet 9. To said key shaft'16 is 'also secured an arm 25 having a pin 20 to engage a slot 27 formed in the upper end of a link 28, to lift the latter, thereby rocking an arm 29 and releasing the pressure rolls 10, 11; said arm 29 belng formed upon a rock shaft 30 having flats 31 to engage rollreleasing arms 32; so that the downward movement of the key .both releases the rolls to permit the free insertion and manipulation bf the sheet, and moves said directrix 13 and stop 12 to operative position.

As soon as the sheet 9 is adjusted, Fig. 9, the key 14 is thrown up, thereby causing the pressuncrolls 10, 11.to bite the sheet and also throwing thedirectrix 1.3 forward to a position of'disuse, so as to permit the sheet to pass up beyond the same and back out of the machine. As soon as the sheet iscompleted, the key 14 is again depressed to permit the removal of lhesheet and the insertionof another sluretyand the operation is upward movement of the key, that'is, from Fig. 9 to F ig. 1, the directrix 13 remains stationary, the movement of the key being accommodated by the loop 22 in the link 19; but continued movement of the key after the-rolls have reached the platen, causes said link 19 toturn the rock shaft 15 and throw the directrix 13 forwardly to a position of disuse, F igi 8. Thus it will be seen that the sheet may .be held against the stop 12 "until it is gripped by the rollers, so that there is no liability of accidental derangement of the sheet after it is adjusted to said stop 12, as has been the case heretofore when the stop has been moved away from the sheet before the latter isclamped by the pressure rolls.

The rock shaft 30 isformed with flats 31, at intervals, and differ from the flats heretofore in use upon the well known Underwood machine, in that they are cut away sufficiently to permit additional rocking of the shaft from the position at Fig. 1, to permit sary to throw the directrix 13 forwardly. In other words, a lost-motion construction is provided between the key 1 1 and rolls 10, 11,

to permit the stop-releasing movement of the key while the rolls remain stationary against the platen.

Yielding means'to detain the rock shaft 15 in either its Fig. 1 or its Fig. 8 position will presently be described. It will be understood thatwhen the arms 32 are opened as at Fig. 3, the rolls 10, 11 are locked mechanically away from the platen, since the arms at this time are caused by their springs. 33 to bear against the cylindrical periphery of the rock shaft 30.

In order to enable the machine to' be used for different kinds of bill heads and to enable the latter to be brought always to the exact point at which the writing is to begin, I provide for adjusting the tablet 7 and the stop 12 up and down, so that the initial position of the sheet may bevaried as re? quired. The plate 7 is for this purpose carried upon a bar or main plate 34, the end ofthe latter secured upon the platen frame ends by means of brackets 35, the latter having slots 36 to receive securing screws 37, to permit forward and backward adjustment of the tablet 7 relatively to the platen. Thumb screws 37 pass through the bar 34: to

ers or guides securedvertically to the back of the plate 7 and havin vertical slots 40 to receive the shanks of t e screw 37, Figs. 7 and 11. Each of the keepers is in the form of a channel bar, the nut being confined in the channel and fitting between the sides thereof, so that it cannot turn.

The rock shaft 15 is mounted partly in extra upward movement of the key, neccsengage nuts 38, the latter confined by keepears 41 on the ends of the tablet 7, and at its extreme right hand end in an ear 42 upon a bracket 43 held by screws t4; against the front face of the bar 34. The'screws at may be loosened" when the tablet 7 is to; be adjusted up ,or down, to permit similar adjustment of the bracket 43; and the screws may be detained at the same time as the thumb screws 37, so that the rock shaft 15 may remain level at alladjustments thereof.

It will be understood that the'sc'rew may be loosened, ,and the link 19 drawn up or thrown down through the block 20 to accommodate the vertical. adjustment just de-' through which pass the shanks of the thumb screws 37, said screws serving to clamp the tappet 7 t9 the bar 34 after the tablet has been adjusted either up or downor along the platen.

The directrix 13 may be slid along the shaft 15 as required, being connected to said shaft to enable the latter always to rock-the directrix. For this purpose the shaft may be formed of rectangular cross section as illustrated, and the directrix may be provided with ears 46 having square holes to lit upon said shaft, Further support for the directrix 13 maybe provided by a small plate 47 secured upon the dire'ctrix about midway between its ends and fitted around.

the shaftlfi and preferabl pressing thereagainst, sufiiciently to ho d the directrix against accidental displacement along the The rock shaft 15 and directrix 13 .are held yieldingly in either the Fig. 8 or shaft.

Fig. 9 position, bymeans of spring fingers 48 secured upon the back ofthe tablet 7 to engage notches 49,, 50 formed in'disk 51 folded at 52 over theears 41, so as to be carried along the bar 15 with the tablet 7. Collars 53 having set screws 54 maybe 10- vided upon said shaft outside of the isks 51 to prevent endwise displacement of the.

tablet 7; The springs 48 engage the notches 49, Fig. 8, when the parts are 1n normal positions, to hold the plate 13 against rattling; and said springs enga e the notches, 50 when the key 14 is fully depressed, as at Fig. 9, to detain the directrix 13 yieldingly in working position, during the manipulation of the sheet 9, and also'until the rolls 10, l l have been restored to normal positions, Fi 1. i

The tzilet'l and'directrix 13 are adjustable to a position in frontof a tally-strip mechanism which is'a'rranged at the right hand end of the platen 1., and constructed substantially as disclosed in 'my application No. 408,235 or No. 402,583, and comprising asegmental platen 55 and tally strip spools 56, 57 mounted upon a bracket 58 rising frdn'ithe platen frame {theflink 28 havinga tooth 59 toengage'a ratchet wheel 60 cured to, a tally-strip winding 813001361, so

that-the strip is advanced line by line, eac11' 1 time that the keyfH is depressed to permit the withdraWalof-the written billand the' z' insertion-ofa new one. i i

, It will be observedlthat -tl 1e stop-ledge or flange- 2 arrested, Figsz' 1 and 9,- -loy engagement with a ledge 62 upon theirear of' the registering plate/i, said ledgegl2 extefid ing back beyond the vertical"face-of the plate 7, to form an abrupt stop, sothat there will beno liability of the edge oft hesheet catching between 12 and 62;-and.'conside'rable space is left between said plate/7 and the upper part of the'directrix 13, to afford a free passage for the paper upto the stop.'

' Variations may be resorted to within the scope of the invention, and portions ofthe improvements may be used without others.
